COMBINED PIPE-FITTING ANI) STEAM-SEPARATOR.

Specification of Letters Patent.

Patented Dec.`2, 1913.

Application led November-'22, 1912. Serial No. 732,905.

To all whom it mayconoem:

Be it known that I, WILLIAM S. Emaorr,

a citizen of the United States, `residing at` Pittsburgh, Allegheny county, State of Pennsylvania, have invented a new and useful:

Improvement in Combined Pipe-Fittings and Steam-separators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification,

in which- Figure l is a side elevation partly broken away, showing one application of my invention; Fig. 2 is a vertical sectional view` of the combined pipe fitting and separator;

Fig. 3 is a view partly in side elevation and partly in vertical section showing another. application of my invention; Fig. 4 is a section taken on the line IV-IV of Fig. 2, but on a reduced scale; and Figs. 5 and (S are vertical sections taken on the lines V-Vand 1 VI-VI, respectively, of Fig. 2, looking in; opposite directions, as indicated by the ar-` steam line at any desired point te perform` the combined oflice `of a pipe fitting and a,

steam separator.

The nature of my invention will be best understood by reference to the accompanying drawings, in which I have shown the preferred embodiment thereof and which will now be described, it being premised, however, that various changes may be made in details of construction and arrangement of the parts, without departing from the spirit and scope of my invention, as defined in the appended claims.

In these drawings, t-he numeral 2 designates a casting which is formed at its lower portion at one side with a steam admission opening 3, and in the opposite side with a steam exhaust opening t, these two openings being connected by a straight through passage. This through passage is formed interiorly of the casting by a curved partition wall 5 of the form best shown in Fig. 6, and by an opening 6 in a vertical separator plate 7 which joins the wall 5. This separator plate is of less width than the width of the casing so as to leave a steam passage 8 at each side thereof, as best shown in Figs. 4

and 5. These `side passages communicate with the chamber 9, above the partition 5, which leads to an outlet opening l0 in the top of the casting. The upper `edggge of plate 7 is 4connected to the front wall of the casting by the downwardly and inwardly inclined wall l1. This wall 1l extends across the interior of the device, as cleanly shown in Fig. 5, so as to prevent a direct escape of .the steam from the chamber l2 into the `outlet l0. The frontor entrance side of the plate 7 is formed with the two series of oppositely inclined separator ribs 13.

A portion `of the steam entering the opening 3 will :pass directly through the yopening 6 and out through the opening 4t; while the balance ofthe `steam will pass through the side openings 8 and upwardly into the chamber 9, and thence to the outlet 10. The steam which goes through the outlet l0 will have had the oil separated therefrom by the separating action of the plate `7 and its ribs 13.

let designates a cavity or depression in the `bottom of the through passage having the drain opening 15.

The device is intended to be used in a steam pipe line which supplies steam to two differentplaces of consumption. Thus, when arranged as shown in Fig. 1, the steam which passes directly through the device goes into a feed water heater, indicated at 16; while the steam which passes upwardly and out through the outlet 10 goes into a pipe 17, which may lead to a heating system. The heater 1G is shown as having a conibined inlet valve and separator plate 1S, which controls the admission of steam to the heater and also separates the oil therefrom. The combined fitting and separator may be located at any distance from the heater, as indicated by the breaking away of the connecting pipe 19, in Fig. 1.

In Fig. 3, I have shown another application of the invention to a case in which the combined valve fitting and separator is applied directly to the inlet of the heater 16. In this figure, I have also indicated the pipe 17:L which communicates with the outlet opening 10, as having a valved branch 17" leading to the heating system, and also as having a relief opening 20, leading to a stack connection 21. The opening 2O is controlled by a relief valve 22, whose stem 23 is engaged by an arm 24: of a rock shaft 25. This rock shaft is counterweighted at one end, as indicated at 26, and is also conq neoted to a dash pot 27. The countervveight and dash pot control the action of the valve 22, whereby it may be made to open, in case of any excessive pressure in the system. The invention is also applicable to a variety of other uses, since it may be inserted at any desired point in the steam line Where it is desired to make a branch connection and to separate the oil from the steam entering the branch connection.

I claim:

l. A combined pipe-iitting and steam separator, having a steam admission chamber therein, and an internal separator Wall or partition forming the forward Wall of said chamber, said Wall or partition eXtending the full height of the chamber but being of less Width than the chamber, there being a through steam outlet passage leading through the Wall or partition, and another steam outlet passage around the Wall or partition; substantially as described.

2. A combined pipe fitting and steam separator, comprising a member having a through steam passage, a separator Wall at substantially right angles to the flow of steam through said passage, and another steam outlet passage around the said Wall, he first named passage having a Water col,-

lecting pocket in its bottom Wall; substan-- tially as described.

3.1%. combined pipe tting and steam separator comprising a casting having a steam admission chamber, a steam passage leading from the said chamber through the opposite side of the casting, and steam passages leading tromV said chamber into anotherV outlet opening, a portion of the Wall of said admission chamber forming the steam separator, substantially as described.

4L. A.. combined pipe fitting and steam separator, comprising a casting having an inlet opening at one side and an outlet opening at the opposite side, a plate member in said casting and having an opening therethrough in line with the inlet and outlet openings, and also having an opening at each side, and an outlet chamber with Which the side openings communicate and which leads to another outlet opening in the casting, substantially as described.

5. A steaml separator comprising a member having inlet and outlet openings connected by a through steam passage, an. internal separator Wall through Which said passage extends, the opening through said Wall being in line with the inlet opening and at least as large in cross-section as the said inlet opening, said member also having a branch steam passage leading from the inlet side of said ivall; substantially as described.

6. A combined pipe fitting and separator, comprising a pipe fitting member having a through steam passage, an outlet chamber above said passage, and a separator plate through which the passage extends, there being steam passages at the sides of said plate communicating With the said chamber, substantially as described.

ln testimony whereof, l have hereunto set my hand.
